Apple today published an intriguing patent application with a unique method for waterproofing future devices — by covering ports, like those for USB or headphones, with self-healing seals.

Described as an, “electronic device with hidden connector,” the invention describes how self-healing elastomeric material could seal each of the ports, which would then be opened by puncturing them with external connectors, such as power or audio feeds, in the event that they needed to be used.

Apple has been taking steps to make the iPhone more water resistant than it has been previously. However, a newly-published patent application suggests the company may go even further — by using cutting-edge electrode technology to actively expel water that has become trapped in the device, rather than just fighting to keep it out.

Although Apple hasn’t confirmed it, there have been rumblings that the new iPhone 6s is more water-resistant than its predecessors. So what better way to make a viral stress test video than to strap every iPhone ever made on a board, lower them into a tray of water, and observe the order in which they stop working?

Done properly, such a concept should let its creator sit back and watch the retirement fund ad revenue roll in. Well, done properly it might. Done incredibly haphazardly, on what looks like the world’s most buoyant piece of wood, it’s not quite such a winner.

Apple hasn’t advertised the iPhone 6s as being waterproof, but it seems that the new handset (unofficially) isn’t totally adverse to taking a dip.

In a new video test, YouTuber Zach Straley submerged both the iPhone 6s and 6s Plus in a bowl of water and let them sit there for an hour, powered up.

While the test certainly isn’t comprehensive — and we recommend all Cult of Mac readers leave their new handsets on dry land — it certainly bodes well if you happen to accidentally drop your iPhone 6s in the bath or down the toilet sometime in the next year.
